Hydroxypropyl methylcellulose (HPMC) is a water-soluble polymer compound that is generally considered an environmentally friendly building material.
Biodegradability: HPMC has good biodegradability in the natural environment, which means that it can be decomposed by microorganisms under certain conditions and eventually converted into environmentally harmless substances. In contrast, traditional plastics such as polyethylene and polypropylene are difficult to degrade and remain in the environment for a long time, causing “white pollution.”
Impact on ecosystems: The way plastic is produced, used and disposed of is polluting ecosystems, endangering human health and destabilizing the climate. The impact of plastic pollution on the ecosystem includes soil pollution, water pollution, harm to wild animals and plants, etc. HPMC, on the other hand, has less long-term impact on the ecosystem due to its biodegradability.
Carbon emissions: Research by Academician Hou Li’an’s team shows that the carbon emissions of biodegradable plastics (such as HPMC) during the entire life cycle are approximately 13.53% – 62.19% lower than traditional plastic products, showing significant carbon emission reduction potential.
Microplastic Pollution: Advances in research on microplastics in the environment indicate that the impact of plastic particles on soil, sediments, and freshwater may have long-term negative impacts on these ecosystems. Plastic particles may be 4 to 23 times more harmful to land than to oceans. Due to its biodegradability, HPMC does not create persistent microplastic pollution problems.
Environmental risks: The economic impact of plastic pollution is significant, with the associated costs of cleaning up plastic waste, implementing waste management systems, and addressing the environmental and health impacts of plastic pollution placing a financial burden on communities and governments. As a biodegradable material, HPMC has low environmental risks.
Environmental impact assessment: In terms of environmental impact assessment, the production and use of HPMC has a small impact on the atmosphere, water and soil, and the cleaner production measures taken during its production process can further reduce the impact on the environment.
As an environmentally friendly material, HPMC has obvious advantages over traditional plastics in terms of environmental impact, especially in terms of biodegradability, carbon emissions and microplastic pollution. However, the environmental impact of HPMC also needs to be comprehensively assessed based on factors such as its specific production process, usage and disposal.
